[435] Defences are not properly lowered from low attribute scores

The BB fighter has average Dexterity and Perception, both 10. When he suffers a reduction of any of this two, the resulting value of the Reflex defence is by 1 point higher than it should be. I did some tests with different builds and spells -- and it looks like this issue holds for all the defences modified by the low sum of connected attributes.

The picture below shows different characters suffering by the bug:

For example, the first character has:
Deflection 25, Fortitude 19, Reflex 19, Will 19
-> Should have:
Deflection 24, Fortitude 18, Reflex 18, Will 18
and so on with others...

How to reproduce:
A) either, by putting Hobbled or similar effect on BB fighter -- the reflex defence will be off;
B) or create a new character from any of those in the picture above or similar (sum of two attributes modifying the tested defence to be < 20);

[comments]
According to several tests with different setups, the bug seems to occur only when the summed modifier from attributes is negative regardless to its value.

For Reflex, Fortitude and Will, there is +2 / -2 modifier to the corresponding defence per point of attribute above / below 10. And at lvl 1 the character will have the base 20 For / Ref / Will, without taking into account modifiers, if I recall correctly.

So if you look at the first sheet, there is already written +0 For from Mig = 10 and -2 For from Con = 9, then it should be For = 20 + 0 - 2 = 18.

Of course, the description and my estimation may be wrong. But your calculation would not work for the last character at all. As he has negative defences;)

Those +0.5 are no longer necessary because the calculation is no longer [Attribute A + Attribute B] x 1.5.

The +0.5 was added because I reported a bug with the rounding for that formula. That formula has now been changed to [Attribute A + Attribute B] x 2, so the cases where you have an odd numbered attribute don't lead to a fractional number anymore.

Bumping for BBv480.

If it's useful, I would like to add that the wrong negative modifier of defences from the sum of attributes doesn't only influence party members, but also enemies. In several instances, as a result of this issue they have a higher defence than should or the defence number isn't lowered enough by used debuff ability/spell.
-> So this time it also works against the player.
